4/4/16 = Square Root Day!!

square_root_square

April 4, 2016 is Square Root Day – so let’s get to the root of it!!

The next square root day won’t be until May 5, 2025, so let’s celebrate! There are only nine square root days in a century – so don’t miss this one!

The square root is an important mathematical concept used in many different occupations – including carpentry, engineering, architects, landscapers, and artists and designers. So, what is a square root? The square root of any number (x) is equal to the number (y) that when multiplied by itself or squared returns the first number (x). In other words, the square root of x is y, because x X x or x²2 is y.

Did you know that the symbol for square root (√) is called the radix or the radical sign? And Christoff Rudolff first used it in 1525?

Maurice Machover wrote a proof poem of the irrationality of √2:

Double a square is never a square, and here is the reason why:
If m-squared were equal to two n-squared, then to their prime factors we’d fly.
But the decomposition that lies on the left has all its exponents even.
But the power of two on the right must be odd: so one of the twos is bereaven.*

 

What fun ways can you find to celebrate this auspicious day? 

How about:
  • Square Dancing
  • Learn to tie a square knot
  • Eat square shaped food – made from root vegetables (what else!?). How about square sweet potato fries, make a square carrot cake!
  • Try root vegetables you might not have eaten before: rutabagas, parsnips, yucca roots, and kohlrabi.
  • Onions, garlic and ginger are also root veggies – find new recipes

Be SURE to come into the library and work on our Color by Numbers (Engineering Style!)

Disover U.S. Patents, Trademarks, and Patent Applications |Workshop Tuesday, April 5, 1pm @Hardin Library

720px-US-PatentTrademarkOffice-Seal_svg

The purpose of this hands-on class is to introduce several resources found on the U.S. Patent & Trademark Office website that may be used to locate information on patents, trademarks and patent applications. Google’s patent searching feature will be also be highlighted as a source for finding information on patents. Taught by Kari Kozak (Head, Lichtenberger Engineering Library).

 

Tuesday, April 5th, 1-2p – East Commons, 2nd Floor, Hardin Library for the Health Sciences

Find nutrition information in PubMed & Embase faster with our workshop | Tuesday, April 5, 10am@Hardin Library

orange-214873_640

Literature searching for nutrition-related subjects in PubMed and Embase can be challenging.

This hands-on session will:

  • examine those challenges and
  • suggest techniques for doing better searches on topics related to nutrition, and
  • improve your search results by using subject headings (MeSH) and advanced keyword searching techniques.

Our next session:
Tuesday, April 5th, 10-11a – East Commons, 2nd Floor, Hardin Library for the Health Sciences

Let’s Go Fly A Kite! A New Exhibit!

Box_kiteLet’s go fly a kitediamond
Up to the highest height!
Let’s go fly a kite and send it soaring
Up through the atmosphere
Up where the air is clear
Oh, let’s go fly a kite!

(from Disney’s Mary Poppins, composed by Richard M. Sherman and Robert B. Sherman)

April is National Kite Month!!

Our new exhibit, Kites! Engineering and Design from Around the World! celebrates kites and all they have contributed to engineering and aeronautics.

The history of kite-flying goes way back – there are differing accounts of when the first written record appeared – varying from about 200 B.C.  to 1000 B.C.  Kites were not toys, but used for delivering messages, carrying lights, noise makers and pyrotechnics to frighten enemy troops. In the 200 B.C. account, Chinese General Han Hsin flew a kite over the walls of a city to determine how far his army would have to tunnel to reach beyond the city’s defenses. Kites were also used for various religious and ceremonial rites. The first known illustration of of the familiar diamond-shaped kite dates from 1618.

Pioneers of aviation used kites to research and test aircraft structures, aerodynamics, and wing designs.  Wilbur and Orville Wright used a specially designed kite to test their control systems. The company Syndicate d’Aviation was founded in 1905. It was first company founded specifically to manufacture airplanes. Their initial product was a two-bay biplane which was inspired by Lawrence Hargrave’s box kite. It is also believed that Leonardo da Vinci’s familiarity with kites led to his invention of the parachute.

So, why are kites, which are heavier than air, able to fly? They rely on lift, drag, thrust, and gravity. Lift results when wind moves across the sail of a kite – the wind pushes up on the kite. At the same time, the wind passing over the top of the kite creates an area of low pressure, which creates pull from behind. Drag is created by wind resistance on the kite’s surface and tail. Gravity and the weight of the kite pull it downwards and the thrust is the power of the wind which creates the lift. A kite needs enough lift to overcome the gravity and drag.

The dihedral angle of a kite is also important. A dihedral angle is the angle formed when two wings come together. If the wings of a kite lean back at the same angle, the wind will push evenly on both wings and it will be perfectly balanced in the sky.

Alexander Graham Bell’s Frost King.

There are many possible kite shapes and how each of them use their aerodynamic features determine if, or how, that kite will fly. In 1905 Alexander Graham Bell developed tetrahedral kites. The giant Frost King had 1,300 individual pyramid-shaped cells arranged in 12 layers and could lift a man 30 feet in the air. We have a smaller (much smaller!!) model of a tetrahedral kite in our exhibit.

 

Remember spending spring and summer afternoons trying to get those kites off the ground or out of ‘kite-eating-trees?’ What is more fun than a wide-open space, a light breeze and a colorful kite? Stop in and see our Kite Flying exhibit, let it get you into the mood and then head out for some spring kite-flying!
